BURNER FOR HEATING-STOVES.

Specification of Letters Patent.

Patented Sept. 6, 1921.

Application filed March 30, 1920. Serial No. 369,877.

To all whom it may concern:

Be it known that I, OLIVER J. RossnLor, a citizen of the U nitedStates,residing at Kokomo, in the county of Howard and State of Indiana, haveinvented certain new and useful Improvements in Burners for Heating-Stoves, of which the following is a specification. I v r This inventionrelates to an oil or gas burner, and while it maybe utilized for anysuitable purpose, it is especially designed for use in connection withheating stoves. The main object of this invention is to provide asimple, economical, durable and efiicient burner to be used for heatingpurposes. v V

Anotherobj-ect of the invention is to so construct the burner that it isself generating; nonwarpable, and will furnish substantially perfectcombustion at either a low or high fire.

. A further object ofthe invention is to provide a flame spreader inconnection with the burner, the said spreader being'lined with asbestoson its under side, and so constructed that it serves a tri-fold purpose,namely; as a spreader for the flame; to protectfthe bottom portion ofthe burner, and being lined with asbestosit acts as a self lighter forthe burner. m

The foregoing and such other ob ects as may appear from the ensuingdescription are .attained by the construction, combination,

arrangement and location of the parts hereinafter more fully described,such as illustrated by the accompanying drawings, and particularly:pointed out in the claims appended hereto, it being understood thatslight changes in the precise construction, proportions and minordetails may be resorted towithout departing from the spirit orsacrificing any of the advantages of th invention. In the accompanyingdrawings forming a part of this specification it will be seen that 1-: VFigure 1, is a central sectional elevation of a heating stove with theimproved burner embodying my invention shown therein, and showing inoutside elevation of the pipe connections broken away in parts, and aportlOll Of the oil tank..'

Fig. 2, is a transverse sectional view taken through the burner on thelines 2-2, Fig. 1, looking in the direction of the arrow, and Fig. 3, ISan inverted plan of the spread- H10 plate detached from the burner.

imilar numerals of reference are employed to designate like partsthroughout the several views of the drawings.

In carryingout my invention, as shown in F 1g. 1, the numeral 1indicates the outer casing of a heating stove of any suitable or desr'able construction, and 2 is the base portlon of said stove. Thenumeral 3 designates the oil or fuel tank which is prefer- I ablylocated about four feet higher than the burner, in order to furnish theproper fuel feeding pressure to the burner, said tank be ing connectedwith the burner by the feed piping 4, provided with a suitable stopvalve 5, and a fuel supply regulating valve 6, said piping 4 beingfixedly connected to the interiorly threaded inlet portion 7 formed atthe bottom portion of the burner 8, which is mounted in any suitable ordesirable manner within the casing 1, at the base portion thereof, themain body portion of the said burner consisting of a single castingformed with an upper arch-shaped member 9, a vertical wall 10 at eachside thereof, and a central inafter described. Formed within the base'member is a horizontal fuel feeding duct 19 which communicates with avertical feeding duct 20 formed in the right hand wall of the burner,said duct 20 in turn communicating with a horizontally positioned duct21 leading from the righthand wall of the burner 100 to the centralportion thereof, and provided with a downwardly extending outlet 21 forthe discharge of the fuel. Arranged centrally of the burner 8 between,its inner wall 11 is a flame spreader plate 22, which is supported uponthe upper surface of the circu- V lar base member 15, and suitablysecured thereto by a plurality of pins 23, which pass throughtheopenings 2 1 and fitted into corresponding openings formed in thebase member. The flame spreader plate 22 is formed with a recessed lowersurface 25 for the reception of the asbestos wicking which is coiledwithin the recessed portion of the said plate in'convolute form witheach of its terminal endportions passing through an orifice 26 formedthrough the said plate, the other orifices 26 being also filled orplugged with asbestos wickingL I p I From the foregoing descriptiontaken in connection with the accompanying drawings, it will be readilyperceived that the oil is first fed through the pipe 4: into thehorizontal duct 19, from thence into the vertical duct 20, thence intothe horizontal duct 21, from'whence it is discharged through the outlet21 into contact with the flame spreader plate 22, and as the oil isdischarged from. the outlet 21 it comesinto contact with a volume of airwhich is passing through the outlet '12 formed through the wall 11, thuscreating a downward blast of commingled air and oil, thereby producing afuel vapor which becomes ignited over the flame spreader plate 22, andproduces an intense heat. I

jVVhenthe burner is first lighted the oil burns on the spreader platewithout emitting smokeor odor until the burner is hot, and as the feedof the oil is increased the flame spreads and burnsthrough theorifices'16,

17 and 18, thus forming a solid blaze substantially over the entirecircle of the 7 burner.

:It' will be obvious that the volume of air flowing into the arched airchamber prevents the arch member from warping, while the orifices 16, 17and 18 formed through the circular base member serve to prevent saidbase member from warping, and the flame spreader plate being lined withasbestos wi'cking, and the openings therethrough being filled with saidwicking it serves to fully 'protect'the base member of the burner andat'the same time the asbestos wicking acts 7 Iasa'self lighter for theburner;

I within the The burner is so constructed that there are no parts likelyto get out of order, and the feeding duct-s may be readily cleaned by removing the screw-threadedplugs 27 fitted I II threaded openings formedthrough portionsrof the burner walls.

it will be understood that it takes fromthree to five minutes for thegas to generate;

having a' series ofopenings of varying sizes therethrough and ahorizontal fuel duct formed therein, a vertical wall formed at each endthereof, one of said walls having a vertical fuel feeding duct formedtherein,

a horizontal fuel feeding duct secured'within said casting, said ductscommunicating with each'other, an arched shaped air chamber forinedbyand within the casting, a downwardly extended fuel feeding outletjwithinsaid air chamber, and air outlet formed in the center of the arch forthe discharge of o the commingled air and fuel.
